The amount of grams of hydrogen that are in the water sample is;
3.985 g
<h3>Avogadro's number</h3>
We are given that;
Number of moles of oxygen in a sample of water = 12 × 10²³
- Now, the chemical formula of a molecule of water is H₂O. This means that for every 1 atom or molecule of oxygen, there must be 2 hydrogen atoms or molecules present.
Since Number of moles of oxygen in the sample is 12 × 10²³, then number of moles of hydrogen will be twice that = 2 × 12 × 10²³ = 24 × 10²³ moles
Now, molar mass of hydrogen is 1 g/mol and we know that;
Molar mass = Avogadro's number(6.023 × 10²³) moles
Thus;
6.023 × 10²³ moles = 1 g/mol
Thus; 24 × 10²³ moles of hydrogen = ( 24 × 10²³ × 1)/(6.023 × 10²³)
⇒ 3.985 g

Answer:
sure and the answer is 1.902071808e+13
Explanation:
The observation that is inconsistent with the ideal gas equation is; "When temperature is held constant and volume increases, the pressure increases."
Boyle's law describes the relationship between the pressure and volume of ideal gas. Boyle's law states that, the volume of a given mass of gas is inversely proportional to its pressure at constant temperature.
Hence, the statement that "When temperature is held constant and volume increases, the pressure increases." does not agree with Boyle's law therefore it is inconsistent with the ideal gas law.
